Answer: 
of an hour.
Step-by-step explanation:
1. You know that it is from 3:12 p.m. (48 minutes before 4:00 p.m.) to 4:30 p.m. (30 minutes after 4:00 p.m.)
2. Therefore, you must make the following addition:
This is 78 minutes out of 1 hour (60 minutes).
3. Therefore, you have the following fraction:
4. Now, you must reduce the fraction:
5. The answer is 13/10 on an hour.
For this case, the first thing you should do is define a variable.
We have then:
x: number of passengers remaining who can board the plane.
We have as data:
1) They can board up to 149 passengers
2) There are 96 passengers currently aboard.
Writing inequality we have:
Answer:
An inequality that can be used to determine how many more people can board is:
Answer:
perimeter of a regular hexagon=6×side length
side length in question is 'k'
perimeter=6×k=6k
Answer:
10π
Step-by-step explanation:
The circumference of a circle is the distance of the outside of the circle. The formula for circumference is C=2πr.
In the question, you are given the diameter. Diameter is the radius times 2. So, to find the radius you can divide the diameter by 2. Since, 10cm/2 is 5 cm, 5cm is the radius.
Then, plug this information into the formula to solve for C.
This means that, in terms of pi, the circumference is 10π cm.
